I just ran a campaign where I had a few hard bounces and soft bounces, but quite a lot of Auto Replies, that, upon further inspection are mostly "Delivery has failed to these recipients or groups:-  The e-mail address you entered couldn't be found".

Is there a way I can delete all those contacts from my mailing lists? There's no point having them in there if they are just going to bounce again. 

Better still, can you improve your hard bounce detection and take them out automatically?
